Abstract
The invention consists in a security paper, as well as the security document obtained with it and the manufacturing process thereof, that combines the security elements called windowed thread with the high contrast single-tone watermark technique. In order to carry out this invention, we make use of the recesses created to cover the thread in the areas where it is visible, which exhibit a greater accumulation of fibers and are therefore opaque areas in the final paper, to insert therein the electrotype or high contrast single-tone watermarks.
